superobject doesn't compile in Delphi 10.2 Tokyo

[aflondono]

In Delphi 10.2 Tokyo, unit superobject.pas stops compiling, with error: "E2036 Variable required" on this line:

if CompareMem(@GetTypeData(TypeInfo).Guid, @soguid, SizeOf(TGUID)) then

This is located in procedure FromInterface inside function TSuperRttiContext.FromJson

This code compiled without issues in Delphi 10.1 Berlin.

I've fixed my local copy by declaring a new variable

var
  varGuid: TGUID;

and then using it like this:

varGuid := GetTypeData(TypeInfo).Guid;
if CompareMem(@varGuid, @soguid, SizeOf(TGUID)) then

and it seems to work correctly in my testing, but I am not sure if this is the correct solution in this case.

You make copy of GUID record, this solution is imho syntactically correct but not optimal (unnecessary memory copying)

you can change it like this

if isEqualGUID(GetTypeData(TypeInfo).Guid, soguid) then
